H67 Title on Ignored Image Failure

Explanation

An img element must follow the guidelines of Success Criterion 1.1.1 (Non-text Content) with regards usage of alt and title attributes.

This example uses empty alt text, but also provides a title attribute. This means that sighted users get a text alternative when they mouse over the image, but users relying on the alt text get nothing. This therefore would not fulfil the Success Criterion, as it means that fully-functioning users see descriptive information that less-functioning users cannot.

This would be typical of situations where an author, noticing that the alt attribute does not provide a tooltip - as it did in early versions of browsers - decides to use the title attribute to provide the tooltip, without providing alt text (or not using an alt attribute at all).
